To the Editor Dr Cappola and Ms Cohen's article 1 highlighted the importance of medical communication. The study of communication dates to ancient Greece when Aristotle first studied the rhetoric of Western civilizations. Modern communication scholars draw from this long and rich history, applying theory and praxis to various contexts.Twentieth-century communication scholars identified 3 subfields of the discipline: interpersonal, organizational, and mass communication. For example, interpersonal communication scholars explore patient-clinician relationships and health outcomes. 2 Organizational communication scholars, who often examine internal communication, study the effects of clinician job stress on individual and small groups, as well as patient outcomes. 3 Mass communication scholars develop and evaluate messages to improve health outcomes. For example, they study public health campaigns such as those designed to reduce smoking. 4 These modern scientists also developed evidence-based communication models, which highlight the deficiencies in the figure depicted by Cappola and Cohen.As communication scientists, we argue that Cappola and Cohen's explanation provides basic strategies for communication but falls short of a patient-centered approach to communication, especially in the interpersonal context in which much of medical communication takes place. Their unidirectional figure "Information Flow in Medical Communication" is reminiscent of the agenda-setting model popular in the late 1960s. The figure does not consider the interactional nature of the patient-clinician relationship. Barnlund's Transactional Model 5 more aptly depicts communication as taking place between individuals who are simultaneously senders and receivers engaged in 2-way communication that involves both an initial message as well as feedback messages. Further, Barnlund's model shows that the ways clinicians and patients send and receive messages is influenced by their social, relational, and cultural experiences. Clinicians and patients have distinct experiences that create opportunities for noise such as stereotypes, which can lead to dissonance and misunderstandings.Communication scientists are specialists who are available for consults and referrals from their medical colleagues.We offer specialized, theoretical, and evidence-driven guidance on the dissemination and implementation of medical evidence. Medical schools around the country embed communication scientists as faculty while others, such as the Penn Medical Communication Research Institute, collaborate with faculty from the Annenberg School for Communication. Communication scientists are uniquely trained to understand the varied contexts in which medical communication occurs. This unique perspective allows us to bridge the gap in understanding the distinct experiences of the clinician and patient, and create relevant, practical, and sustainable health solutions that improve quality of life for our patients and communities.
